Installation for programmed dyeing of threads, ribbons and similar

ABSTRACT

The invention pertains to a method for programmed dyeing of threads, ribbons and similar, whereby the threads are moved along mutually close parallel tracks opposite to at least one dye supply and, depending on the program selected, a relative motion is caused between said moving threads and the dye supply with the purpose of having these threads and the dye come temporarily into contact, or of removing them one from another.

This can be achieved according to the invention b means of applying a working method that consists mainly in moving the threads closely along mutually parallel tracks opposite to at least one dye supply and, depending of the program selected, in causing relative movements between the specified moving theads and the dye supply in order to bring said threads and the dye temporarily in touch or remove them one from another. 7

Threads dyed in this manner will be preferably wound onto a beam or, individually, onto a series of numbered reels.

Such beams or reels will then allow for manufacturing a textile product with a very definite pattern.

This will now allow, for instance, for manufacturing gummed carpets in a very large range of patterns or color effects.

One of the numerous possible designs of the invention will be detailed as an example hereinafter, with reference to the schematic lateral view hereto-attached of an installation according to the invention.

As shown by the drawing, the threads 1 to be dyed of a beam 2 will bemoved over guide rolls 3, 4 and 5 to a pick-up beam 6 along mutually close parallel tracks. Well-known means (not shown) have been provided for winding threads 1 continuously or step-by-step onto beam 6, preferably with an adjustable speed system, and for keeping the strain and strain variations of threads 1 within acceptable limits. Preferably, a warp stop motion will also be used.

Threads 1 will thus be moved above one or better several dye supplies. In the design shown, a dye supply consists of a vat 7 fitted cross-wise as compared to the threads. In this vat a rotary barrel 8 has-been assembled to be rotated continuously by adequate means and, preferably, with adjustable rotating speed.

An L-shaped rake 9 is hinged with one of its extremities 10 to one wall of the vat. The other lateral extremity ll of this rake will rest on the uppermost part of barrel 8 and can, if desired, be pushed or pulled to this position by means of a spring or springs. Means should be preferably provided for in order to give this rake 9' into vat 7. in front of each vat 7, as compared to the direction of motion of threads 1, a series of loops 15, has been assembled, the number of which will correspond preferably with the number of threads. This, however, does not prevent several threads from being drawn through the eye of one and the same loop.

Loops 15 will be controlled individually or in groups by a programming unit 16, e.g. of thelacquard type, and pulled to their lowest position through weightloads or springs 17. Upon leaving a dye supply area. threads '1 will be moved through a drying and/or heating system 18 fitted, in this example, with infra-red lamps l9 and with an air suction system 20. V It is obvious that, as compared to each dye supply 13, the threads 1 or groups of threads can each take two positions, depending on the position of corresponding loop 15 or, consequently, according to the program. In the first or high position, threads 11 will remain removed from rim 14 of rake 9. In the second or low position, they will touch said rim and they will be thus locally dyed over a length depending on the threads speed of motion and on the length of time during which the loop or loops will remain in low position.

In case of several dye supplies 13, the programming systems will be synchronized in conformity with: the afore mentioned speed of motion; the clearance between a loop 15 and corner 14 of the corresponding rake 9; the clearance between two successive corners l4; and the succession of signals, their nature and duration.

In order to achieve accurate adjustment, rakes 9 may be made, for instance, adjustable so that the position of their corner M can be shifted laterally. Complete vats 7 should also allow forbeing assembled on rails in order to allow for lateralshifting of these vats and thus for the adjustment of mutual clearance between the casings. It is self-evident, that numerous other designs of the invention will be possible. We can, for instance, imagine a system in which, instead of barrels 8, rakes 9 and loops 15, the programming units 16 will be assembled directly above vats 7 while carrying every now and then, in accordance with the program, a small volume of dye to specific threads.

Instead of one or of both beams 2 and 6 one could use reels, in which case the reels replacing beam 6 will have to be numbered.

The invention also covers yarnbeams, the threads of which were dyed according to the working method detailed hereabove, and textile products obtained by means of such threads to be considered as novel industrial products.
